SMOKING PIPE rving Anderson and-Glenn P. Anderson, Lodi, Calif.

Application October 4, 1946, Serial No. 701,324

2 Claims.

This invention relates to an improved construction of smoking pipe and more particularly to a pipe of extremely simple construction capable of being readily cleaned while the bowl thereof is filled with burning tobacco and without the use of a tool or pipe cleaner. A

Another object of the invention is to provide a pipe that will insure the smoker a clean, dry smoke and which will prevent the accumulation of moisture in the base of the bowl producing a wet heel.

More particularly, it is an object of the invention to provide a pipe which is so constructed that by means of a slight pressure with the thumb and index finger on portions of the pipe any accumulated moisture in the stem or bit may be readily expelled from the pipe, by blowing through the bit and stem in a direction toward the bowl to thus clean the pipe with only a momentary interruption of the smoking thereof. Y

Still a further object of .the invention is to provide a pipe which, when being cleaned, is closed as to the passage between the 'bit and bowl so that there will be no possibility of sparks or ashes being blown out of the bowl.

Still a further aim of the invention is to provide a pipe which is so constructed that by the ready removal of one part thereof, access will be afforded to the pipe passages capable of becoming clogged, for readily removing any obstructions therefrom and for facilitating the maintenanceof the pipe in a clean-and sanitary condition.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawings, illustrating a preferred embodiment thereof, and wherein:

Figure 1 is a longitudinal, .substantially central Vertical sectional View of a pipe constructed in accordance with the invention Yand shown in its normal condition for use in smoking;

Figure 2 is a fragmentary view similar to Figure 1 but showing the pipe with parts thereof in adjusted position for expelling moisture from the pipe stem and bit, and

Figure 3 is a cross-sectional View taken substantially along a plane as indicated by the line 3 3 of Figure 1.

Referring more specifically to the drawing, the

2 numeral 5 designates the improved pipe in its entirety and which includes a bowl 6, a stem, designated generally l, forming an integral part of the bowl 6, and a bit 8.

The stern 'l is provided with an upwardly and rearwardly inclined bore which is disposed adjacent to the bowl vE and a portion of which is closed by a plug 9 to form an upper bore portion I'El, which opens outwardly of the upper side of the stein l and a lower bore portion Il, which opens outwardly of the under side of the stem l. The stem l is reamed out from the under side thereof .and intermediate of its ends to form a relatively large chamber l2 and a perpendicular passage I3 which has one end opening' outwardly of the upper side of the stem 'l and its opposite end opening into the chamber l2. Said last-mentioned end of the passage i3 is caused to open into the chamber I2, adjacent the lower part thereof, by a perpendicular, depending baille lll, which forms an integral part of the stem 'l and which extends from the top to a point intermediate of the top and bottom thereof. After the stem 'l has been reamed out to form the chamber l2, passage I3 and baille M, the bottom of the chamber is closed by a plate or closure I5, which may be of the same material as the stem l and which is relatively thin and is disposed with its outer side, ush with the under side of the stem "l,

The lower part of the bowl 5, beneath the heel of the hollow interior thereof and the adjacent part of the stem 'l is drilled to form a bore which intersects with the bore l! and which is closed by a plug or insert I6 from the outer side of the bowl 6 to the adjacent side of the passage Il to thus form a passage ll in the bottom of the stem 'l which communicates at one end thereof with the bore or passage i i and which opens, at its opposite end, into the lower part of the chamber I2.

The stem 'l is provided with a recess I8 at its outer end to receive the nipple i9 of the bit 8 and said stem is provided with a longitudinal bore 26, which is disposed substantially axially thereof and which extends from the rear end of the chamber l 2 to the recess i8 and which aligns and communicates with a bore 2| which extends longitudinally Vthrough the bit 8.

A bore is drilled through the stem l, between the bowl 6 and chamber I2, substantially in alignment with the bore or passage 20 and said bore intersects with the passage I and is closed by a plug or insert 22 between the chamber I2 and passage I0 to form a short passage 23 which communicates at one end with the lower end of the passage I0 and at its opposite end with the base or heel of the hollow interior of the bowl 6.

A cover or housing 24 is disposed over a portion of the upper part of the stem 1 and adjacent the bowl 6 and is open on its under side and is of a length so that the passages I0 and I3 will open into the housing or cover 24, when the latter is in an applied position, as seen in Figures l and 2. The cover or housing 24 is detachably retained on the stem 1 by screw 25 which extends downwardly therethrough and which threadedly engages an upwardly opening recess 26 in the stem 1. The stem 1, between the passages I0 and I3 and adjacent the latter, is provided with an upstanding bale 21 which is disposed within the housing 24 and which extends from side to side thereof and to a point adjacent the top of the housing so that the smoke from the bowl 6 in passing from passage I0 to passage I3 through housing 24 is deilected over the bale 21. A frustro-conical valve 28 is disposed within the housing 24 above the upper end of the passage I3 and is provided with a valve stem 29 which extends reciprocally through the top of the housing 24 and terminates in an enlarged head 30 which is disposed thereabove. An expansion coiled spring 3I is carried by the valve stem 29, between the housing 24 and its iinger plate 30, for normally holding the frustro-conical valve body 28 in a retracted, raised position out of engagement with the passage 30, as best seen in Figure l.

A bracket 32 is secured to and depends from the underside of the stem 1, intermediate the ends of the bore or passage I1, to provide a support for a lever 33 which is pivotally mounted thereon, intermediate its ends. The lever 33 is provided on its upper side and at one end thereof with a pad or valve head 34 which is normally retained in a position to close the outer end of the bore or passage I I by an expansion spring 35 which is disposed 'between the stem 1 and the opposite end of the lever 33, as best seen in Figure l.

From the foregoing, it will be readily apparent that the springs 3l and 35 will normally function to retain the valve 28 and valve 34, respectively, in open and closed positions, respectively, as seen in Figure l, so that assuming the bowl (i to be iilled with tobacco and the tobacco ignited, the smoke therefrom can be drawn by suction in the bore 2I through passage 23 and passage I0 into and through the housing 24 over the bafe 21, through passage i3 into chamber I2 and from chamber I2 through passages 20 and 2I to the smokers mouth. A substantial part of the moisture carried by the smoke will be trapped either by the baille 21 or by the chamber I2. When it becomes apparent that moisture has begun to accumulate in the passages '29 and ZI, the smoker, by the simple expedient of pressing on the valve finger plate 30 with the index finger and on the lever 33, beneath the spring 35, with the thumb, can move the valve 28 to a closed position and the valve 34 to an open position, as seen in Figure 2. With the valves thus arranged, the smoker can blow back through the passages 20 and 2l .to

cause any moisture therein and in the chamber I2 and passage I1 to be expelled through the drain passage II, as illustrated by the arrows 36, Figure 2. It will thus be readily apparent that this cleaning operation can be accomplished very rapidly and while tobacco is burning in the bowl 6 and without the possibility of blowing ashes or sparks from the bowl. Likewise, it will be readily apparent that the trap chamber I2 and trap passage I1 will provide a stump for the accumulation of moisture which passes beyond the housing 24 t0 prevent such moisture draining back into the bowl 6 and thus prevent a wet heel.

The pipe 5 may be thoroughly cleaned by removing the fastening 25 so that the housing 24 can be detached after which the interior of the housing can be wiped out and the upper surface of the stem, normally covered thereby, can be wiped off as well as cleaning of the baille 21. A pipe cleaner can be passed through the passages IG and 23 and the passage I3 to clean these passages and remove any obstruction therefrom,

and a pipe cleaner may also be passed through the passages 20 and 2I so that when the housing 24 is reassembled on the stem 1, the smoke passing between the bowl 6 and the passage 2| of the.

bit 8 will be entirely clean.

Various modifications and changes are contemplated and may obviously be resorted to, without departing from the spirit and scope of the invention as hereinafter defined by the appended claims.

We claim:
